My Collection ENGAGE-418 patch

[Svetoslav Nedkov]

Hi Colin, Justin,

I have reworked My Collection to support language switching. This 
involved changing the Lucene CouchDB view to support language queries as 
well as the native Couch view to return the McCord artifact ID.
Another change is the new parametrized  view in Engage config file that 
limits the returned documents to 256, otherwise CouchDB Lucene returns 
25 documents as a maximum.
When querying for artifacts by McCord ID the documents are returned in 
the order they were processed, i.e. by their UUID, so I had to reorder 
the artifacts in My Collection service.

Here is the Lucene view with language index:

   "by_id": {
       "defaults": {
           "store": "no"
       },
       "index": "function(doc) {var ret=new Document(); 
ret.add(doc.artifact.id); ret.add(doc.artifact.lang); return ret;}"
   }


The native view that returns the McCord ID:

function (doc) {
    var artifact = doc.artifact;
    emit({
        'accessNumber': artifact.label.accessnumber,
        'lang': artifact.lang
    }, {
        'title': artifact.label.title || artifact.label.object,
        'artist': artifact.label.artist,
        'dated': artifact.label.dated,
        'medium': artifact.label.medium,
        'dimensions': artifact.label.dimensions,
        'mention': artifact.label.mention,
        'accessnumber': artifact.label.accessnumber,
        'description': artifact.description || "",
        'mediaCount': artifact.mediafiles ? 
artifact.mediafiles.mediafile.length.toString() || "0" : "0",
        'media': artifact.mediafiles ? artifact.mediafiles.mediafile || 
[] : [],
        'commentsCount': artifact.comments ? artifact.comments.cnt || 
"0" : "0",
        'comments': artifact.comments ? artifact.comments.comment || [] 
: [],
        'relatedArtifactsCount': artifact.related_artifacts ? 
artifact.related_artifacts.cnt || "0" : "0",
        'relatedArtifacts': artifact.related_artifacts ? 
artifact.related_artifacts.artifact || [] : [],
        'image': artifact.images ? artifact.images.image : [],
        'artifactId': artifact.id
    });
}
